This is exactly the viewpoint I have as well. I have missed some very important emails before, such as instructions for an interview, acceptance emails, etc... They don't even show up in Gmail's search system, because it doesn't search through spam. This has forced me to look through all of the spam I get daily, examining each one to make sure I'm not missing something important. Gmail may as well not filter spam at this point.
